主题：请教：树和表的筛选问题

 看不懂你想表达什么意思。参考代码，全局的click事件

If e.Sender.Name.StartsWith("rbtn") Then
    Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
    Dim nd As WinForm.TreeNode
    Dim tb As DataTable = DataTables("用户")
    Dim dt As DataTable = DataTables("部门")
    tr.StopRedraw()
    tr.Nodes.Clear
    Dim dr As DataRow
    Select Case e.Sender.Name
        Case "rbtn全部"
            tr.Nodes.Add("全部")
            For Each dr In dt.Select("部门id in (" & tb.GetComboListString("部门ID", "范围 = '全部'").Replace("|", ",") & ")")
                nd = tr.Nodes.Add(dr("部门ID"),dr("部门"))
                nd.Tag = dr("部门ID")
                Functions.Execute("递归",nd,dt)
            Next
        Case "rbtn本部门"
            For Each dr In dt.Select("部门id in (" & tb.GetComboListString("部门ID", "范围 = '本部门'").Replace("|", ",") & ")")
                nd = tr.Nodes.Add(dr("部门ID"),dr("部门"))
                nd.Tag = dr("部门ID")
                Functions.Execute("递归",nd,dt)
            Next
        Case "rbtn本部门及子部门"
        Case "rbtn上级部门"
        Case "rbtn上级及本部门和子部门"
        Case "rbtn子部门"
    End Select
    tr.ResumeRedraw
End If
